TECHNICAL FIELD

The present disclosure relates to the technical field of photoelectricproducts, in particular to a cover plate module.

BACKGROUND

With the arrival of the age of commercialized 5G, more and more 5G basestations are being built to provide wireless coverage and realizewireless signal transmission between wired communication networks andwireless terminals. The architecture and form of the base stationsdirectly affect how 5G network is deployed. In the current technicalstandards, the frequency band of 5G is much higher than that of 2G, 3Gand 4G networks. At present stage, the 5G network mainly works in thefrequency band of 3000-5000 MHz. Because the higher the frequency, thegreater the attenuation during the propagation of signals, the densityof the base stations of the 5G network should be higher.

Because the attenuation of 5G signal is particularly serious, therequirements for the structure of the antenna and the reception andtransmission of the antenna are becoming higher and higher. For example,there may be great impact on the traditional mobile phone antenna with adisuse of the metal back cover. The antenna has to be moved outward toenhance the reception and transmission of the signal. Moreover, becausethe signal is very easy to attenuate, the glass of buildings may need tobe used as the base station of the signal, but it cannot affect thelight transmission, which requires a new antenna structure to be used ona device and the base station.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to make objects, technical details and advantages of thepresent disclosure more apparent, the present disclosure will be furtherdescribed specifically with reference to the accompanying drawings andembodiments. It should be understood that, the specified embodimentsdescribed herein are only used to explain the present disclosure, butnot to limit the present disclosure.

In the description of the present disclosure, unless otherwise clearlyspecified and limited, the terms “first” and “second” are only used forthe purpose of description and should not be understood as indicating orimplying relative importance; unless otherwise specified or stated, theterm “multiple” refers to two or more; and the terms “connection” and“fixed” should be understood in a broad sense. For example, “connection”is a fixed connection, a detachable connection, an integratedconnection, or an electrical connection, and is connected directly orindirectly through intermediate media. For those skilled in the art, thespecific meanings of the above terms in the present disclosure areunderstood according to specific situations.

The present disclosure provides a transparent antenna, including: asupporting body or a supporting layer, which is made of polymer materialor glass and is mainly used as a support of an antenna; a transparentantenna including an antenna body and a partition region, in which aside of the supporting layer is provided with a grid-like conductivewire to form the antenna body, and the transparent antenna is visuallytransparent and is actually made of a conductive material, but lines arethin enough for human eyes to distinguish; and a dummy electrode. Thepartition region is provided with a grid to form the dummy electrode,and the dummy electrode is electrically insulated from the antenna body.Of course, the dummy electrode may also be random line segments. Becausethe transparent antenna is made of a conductive material, which willaffect the transmittance to some extent, in other words, there is adifference in the transmittance between a region with the transparentantenna and a region without the transparent antenna resulting in visualdifference of human eyes. Therefore, the dummy electrode is provided inthe partition region of the transparent antenna, and the dummy electrodecannot function as an antenna. The material of the dummy electrode maybe the same as the material of the transparent antenna, and the materialof the dummy electrode may be a conductive material or a non-conductivematerial. Moreover, in the case where the dummy electrode includesrandom or regular line segments, the line segments may be overlapped, orall line segments may be independent and not intersect with each other.And of course, the extension lines of the line segments may intersectwith each other.

For example, the absolute value of the difference between thetransmittance of the antenna body and the transmittance of the dummyelectrode is not greater than 20%. Furthermore, the absolute value ofthe difference between the transmittance of the antenna body and thetransmittance of the dummy electrode is not greater than 10%, or theabsolute value of the difference between the transmittance of theantenna body and the transmittance of the dummy electrode is not greaterthan 5% in order to achieve a smaller difference in visual effect.

In an embodiment of the present disclosure, the conductive wire of thetransparent antenna is protruded on the supporting layer. Of course, theconductive wire may also be embedded on a side of the supporting layer.In the case where the transparent antenna is an embedded structure, itis equivalent to that a side of the supporting layer is provided with aconcave structure, the concave structure forms a grid, and the concavestructure is provided with a conductive material to form the conductivewire embedded on the side of the supporting layer. The height of theconductive material is less than the depth of the concave structure; orthe height of the conductive material is equal to the depth of theconcave structure; or the height of the conductive material is greaterthan the depth of the concave structure.

For example, the concave structure includes a bottom surface, two sidesurfaces and an opening, and a black material is provided close to thebottom surface and/or the opening. That is, the bottom of the conductivematerial in the concave structure is provided with the black material,or the top of the conductive material in the concave structure isprovided with the black material, or both the bottom and the top of theconductive material in the concave structure are provided with the blackmaterial. Of course, the black material itself may also be conductive.An included angle between each of the two side surfaces and the bottomsurface is not equal to 90 degrees. Of course, the included anglebetween each of the two side surfaces and the bottom surface may also beequal to 90 degrees or less than 90 degrees.

In an embodiment, the grid which forms the dummy electrode includesmultiple grid lines, and at least one of the grid lines is disconnected,so that the grid line is disconnected to prevent the dummy electrodefrom being connected with the antenna body. In this way, the grid of thedummy electrode is disconnected, which further ensures the safety of theantenna body. The grid lines are made of a conductive material and/or anon-conductive material, and the grid lines are embedded in thepartition region. Therefore, the grid of the dummy electrode is a convexstructure or an embedded structure, and is formed synchronously with theantenna body or is formed by separate processes. The difference betweenthe dummy electrode and the antenna body is that the antenna body playsa role of an antenna, such as receiving and transmitting signals, whilethe dummy electrode does not need to play the role of the antennaitself.

Referring to FIG. 1, a transparent antenna array 100 includes atransparent antenna 10, and the transparent antenna 10 includes anantenna body 11 and a partition region 20. It is illustrated in FIG. 1that a single transparent antenna 10 itself includes an antenna body 11and a partition region 20, and there is also a partition region 20between multiple transparent antennas 10. In this way, the singletransparent antenna 10 includes the antenna body 11 and the partitionregion 20, and the partition region 20 is provided with a dummyelectrode. The dummy electrode includes a grid or line segments, and thedummy electrode is electrically insulated from the antenna body. Theremay also be a partition region 20 between multiple transparent antennas10, the partition region 20 may also be provided with a dummy electrode,and the dummy electrode includes a grid or line segments. Moreover, thegrid or line segments composing the dummy electrode may be connected, orthe grid lines composing the grid are disconnected. In the case wherethe line segments are used to compose the dummy electrode, the linesegments are intersect or not intersect with each other.

Referring to FIG. 2, a transparent antenna is disclosed, and thetransparent antenna includes a supporting body 30, a polymer layer 40,an antenna body 11 and a shielding layer 50.

The side of the polymer layer 40 provided with the antenna body11 is further provided with the shielding layer 50. The shielding layer50 is made of colored ink or other colored shielding materials forshielding. Of course, the transparent antenna applying the structureshown in FIG. 2 may also be provided with a dummy electrode (not shownin the figure). The structure in FIG. 2 may be used as cover plates ofsome electronic devices or as cover plates of some household appliancesin practical applications, for example, the structure is used in mobilephones, PADs, watches, televisions and other devices that need antennas.

Referring to FIG. 3, another product structure of a transparent antennais disclosed, and the transparent antenna includes a supporting body 30,a polymer layer 40, an antenna body 11 and a shielding layer 50. Thesupporting body 30 is made of glass, PMMC, PET, PC, PE or compositeboard. A side of the supporting body 30 is provided with the shieldinglayer 50, which is made of colored ink or other colored shieldingmaterials for shielding. The side of the shielding layer 50 away fromthe supporting body 30 is provided with the polymer layer 40, and theside of the polymer layer 40 away from the shielding layer 50 isprovided with a concave structure. The concave structure is providedwith a conductive material to form the antenna body 11. Of course, theantenna body 11 may also be a convex structure (not shown in thefigure). Of course, the transparent antenna applying the structure inFIG. 3 may also be provided with a dummy electrode (not shown in thefigure). Moreover, if the supporting body 30 is an using surface (orcalled as a user surface), because the antenna body 11 is shielded bythe shielding layer 50 and the antenna body 11 can not be seen in uservision, the antenna body 11 may also be non-transparent, or thetransmittance of the transparent antenna does not need to beparticularly high, for example, the transmittance is 20%, 40%, or 70%.Of course, the transmittance of the transparent antenna may be similaror the same as the transmittance of the transparent antenna towards theuser surface, for example, greater than 85%, or greater than 90%, oreven higher, greater than 92%. The product structure in FIG. 3 may alsobe applied to cover plates of some electronic devices, as well as coverplates of some household appliances, or used in vehicles and buildings,for example, the structure is used in mobile phones, PADs, watches,televisions and other devices that need antennas.

Referring to FIG. 4, another embodiment of a transparent antenna isdisclosed. The transparent antenna includes a supporting body 30, apolymer layer 40, a transparent antenna 10 and a dummy electrode 20. Thepolymer layer 40 is provided on a side of the supporting body 30, theside of the polymer layer 40 away from the supporting body 30 isprovided with a concave structure, and the concave structure is providedwith a conductive material to form the transparent antenna 10 and thedummy electrode 20. The transparent antenna 10 includes an antenna body11 and a partition region, and the antenna body 11 includes a grid-likeconductive wire. The dummy electrode is provided in the partition regionand includes a gird or line segments, and the grid includes multiplegrid lines 21. The absolute value of the difference between thetransmittance of the antenna body and the transmittance of the dummyelectrode is not greater than 20%. For better visual effect, theabsolute value of the difference between the transmittance of theantenna body and the transmittance of the dummy electrode is not greaterthan 10%, or not greater than 5%.

The transparent antenna 10 and the dummy electrode 20 shown in FIG. 4are both concave structures. The antenna body 11 of the transparentantenna 10 may be embedded in the polymer layer 40, in which theembedding refers to that the conductive material is provided in theconcave structure with the thickness of the conductive material beingless than the depth of the concave structure, or being equal to thedepth of the concave structure or being higher than the depth of theconcave structure. The antenna body 11 of the transparent antenna 10 mayalso be a convex structure. Of course, the grid lines 21 of the dummyelectrode 20 may also be a convex structure. And the dummy electrode mayalso include line segments, and the line segments may be independent andnot intersect with each other, or may be overlapped with each other. Inthe case where the dummy electrode includes a grid, the grid linescomposing the dummy electrode 20 are electrically disconnected, so thatthe grid lines of the dummy electrode 20 are not conductive.

The transparent antenna disclosed in FIG. 4 can be used on electricaldevices, including electronic devices with display function, such asmobile phones, PADs, etc. The transparent antenna may be directly formedin a display region in front of a mobile phone, in this case, thesupporting body 30 is made of glass, and the transparent antenna 10 isprovided below the glass, so that the display region of the mobile phonecan also be used to provide the receiving and transmitting terminals ofthe antenna, without affecting the normal use and viewing of the mobilephone. Of course, the structure may also be applied on a back cover ofthe mobile phone, and is provided under the glass or composite plate ofthe back cover of the mobile phone, which does not affect the appearanceof the back cover of the mobile phone. In addition, the transparentantenna may also be applied on windows of vehicles. With thecommercialization of 5G, the number of signal base stations increasessharply, and 5G signal is easy to be shielded. Therefore, thetransparent antenna can be formed on the windows (such as glass, PMMA orother transparent materials) of vehicles, such as the glass of the carwindow, the glass of the high-speed rail, etc., which can well ensurethe reception and transmission of the signal. The transparent antennamay also be used on glass of buildings or components with transmittance.Moreover, the transparent antenna may be directly formed on glass, ormay be bonded to the glass or transparent medium through bonding.

Referring to FIG. 5, another structure of a transparent antenna isdisclosed. The transparent antenna includes a supporting body 30, apolymer layer 40, a protective layer 60, a transparent antenna 10 and adummy electrode 20. The polymer layer 40 is provided on a side of thesupporting body 30, the side of the polymer layer 40 away from thesupporting body 30 is provided with a concave structure, and the concavestructure is provided with a conductive material to form the transparentantenna 10 and the dummy electrode 20. The transparent antenna 10includes an antenna body 11 and a partition region. The antenna body 11includes a grid-like conductive wire, and the dummy electrode 20 isprovided in the partition region. The dummy electrode includes a grid orline segments, and the grid includes grid lines 21. And the absolutevalue of the difference between the transmittance of the antenna bodyand the transmittance of the dummy electrode is not greater than 20%.For better visual effect, the absolute value of the difference betweenthe transmittance of the antenna body and the transmittance of the dummyelectrode is not greater than 10%, or not greater than 5%. The side ofthe transparent antenna 10 and the dummy electrode 20 away from thesupporting body 30 is provided with the protective layer 60. Theprotective layer 60 may be made of a material with a hardness not lessthan 2H. Of course, the protective layer 60 may also be made of amaterial like transparent leather, so the protective layer 60 may bemade of a UV material, a PU material, a TPU material, etc.

Referring to FIG. 5, in the transparent antenna structure of FIG. 5, thetransparent antenna 10 and the dummy electrode 20 are both directlyprovided on the user surface, and the protective layer needs to beprovided on the surface of the transparent antenna to protect thetransparent antenna structure from being damaged. Moreover, thestructure has no location limitation. Taking a mobile phone as anexample, the transparent antenna of this structure is provided under ascreen cover, and is also provided above the screen cover, or isprovided under glass of the back cover of the mobile phone, or isprovided directly outside the back cover of the mobile phone. Thetransparent antenna structure shown in FIG. 5 is very advantageous foruse in car windows, buildings, etc., and can be well used as an antennaof a base station or as an antenna for communication.

Referring to FIG. 6, another embodiment of a transparent antennastructure is disclosed. The transparent antenna includes a supportingbody 30, a first polymer layer 40 (the “first” here is only forconvenience of description, and can also be referred to as the polymerlayer 40), a second polymer layer 41, a first transparent antenna and asecond transparent antenna. The first polymer layer 40 is provided onone side of the supporting body 30, and the side of the first polymerlayer 40 away from the supporting body 30 is provided with a concavestructure. The concave structure is provided with a conductive materialto form the first transparent antenna, the first transparent antennaincludes an antenna body 11 (can also be referred to as a “first antennabody”) and a partition region, and the antenna body 11 includes agrid-like conductive wire. The second polymer layer 41 is provided onone side of the first polymer layer 41, and the side of the secondpolymer layer 41 away from the first polymer layer 40 is provided with aconcave structure. The concave structure is provided with a conductivematerial to form the second transparent antenna, the second transparentantenna includes antenna body 12 (can also be referred to as a “secondantenna body”), and the antenna body 12 includes a grid conductive wire.And the projection of the second transparent antenna covers at least 60%of the area of the partition region of the first transparent antenna, orcovers 80% of the area of the partition region of the first transparentantenna, or covers more than 95% of the area of the partition region ofthe first transparent antenna in order to achieve better visual effect.The partition region described here is a partition region of a singletransparent antenna, or a partition region between two transparentantennas. In the present embodiment, the first transparent antenna andthe second transparent antenna cooperate with each other to “fill” theirrespective partition regions, in which the partition regions may becompletely “filled” or partially “filled”, in order to reduce visualdifference caused by difference in transmittance. Of course, in the casewhere there is an overlapping region between the first transparentantenna and the second transparent antenna, in order to ensure a similartransmittance, the grid linewidth at the overlapping region is less thanthe grid linewidth at a non-overlapping region, so as to ensure that thetransmittance at the overlapping region is similar to the transmittanceat the non-overlapping region. For example, the grid linewidth at theoverlapping region of the antenna body 11 of the first transparentantenna is 3 microns, while the grid linewidth at the non-overlappingregion of the antenna body 11 is 5 microns, so that the absolute valueof the difference between the grid linewidth at the overlapping regionand the grid linewidth at the non-overlapping region is not less than0.5 microns. Of course, the same is true for the second transparentantenna.

Referring to FIG. 7, another transparent antenna structure is disclosed,the structure is obtained from a change of the structure shown in FIG.6, in which the first polymer layer 40 and the second polymer layer 41are respectively provided on both sides of the supporting body 30.Therefore, the first transparent antenna and the second transparentantenna are located on both sides of the supporting body 30, and theother structures are similar to the structure shown in FIG. 6.

The structures of the transparent antennas shown in FIG. 6 and FIG. 7are both applicable for mobile phones, PADs, household appliances,buildings and vehicles.

Referring to FIG. 8, another embodiment discloses a transparent antenna.The transparent antenna includes a supporting body 30, a polymer layer40 and a covering layer 31. The polymer layer 40 is provided on a sideof the supporting body 30, a concave structure is provided on the sideof the polymer layer 40 away from the supporting body 30, and theconcave structure is provided with a conductive material to form thetransparent antenna. The transparent antenna includes an antenna body11, and the antenna body 11 includes a grid-like conductive wire. Thecovering layer 31 is provided on the side of the polymer layer 40 awayfrom the supporting body 30. Both the covering layer 31 and thesupporting body 30 are made of glass, or the material of the coveringlayer is different from the material of the supporting body, so that thetransparent antenna is located between the covering layer and thesupporting body. For example, there are many double-layer glass inarchitectural glass allowing the transparent glass structure to beprovided between two layers of glass, and there are many structures withan interlayer in window glass of vehicles.

Referring to FIG. 9, another transparent antenna is disclosed. Thetransparent antenna includes a supporting body 30, a polymer layer 40,an optical interlayer 70 and a covering layer 31. The polymer layer 40is provided on a side of the supporting body 30. The side of the polymerlayer 40 away from the supporting body 30 is provided with a concavestructure, and the concave structure is provided with a conductivematerial to form a transparent antenna and a dummy electrode. Thetransparent antenna includes an antenna body 11 and a partition region,and the antenna body 11 includes a grid-like conductive wire. The dummyelectrode is provided in the partition region and includes a grid orline segments, and the grid includes grid lines 21. The absolute valueof the difference between the transmittance of the antenna body and thetransmittance of the dummy electrode is not greater than 20%. For bettervisual effect, the absolute value of the difference between thetransmittance of the antenna body and the transmittance of the dummyelectrode is not greater than 10%, or not greater than 5%. Both thecovering layer 31 and the supporting body 30 are made of glass, or thematerial of the covering layer is different from the material of thesupporting body, so that the transparent antenna is located between thecovering layer and the supporting body. The structures of the dummyelectrode and the transparent antenna here are the same as thatdescribed above. The optical interlayer 70 is located between thepolymer layer 40 and the covering layer 31. The optical interlayer 70may be a vacuum layer. Of course, the optical interlayer 70 may also bemade of an optical glue, so that the covering layer 31 can be bondedwith the polymer layer 40, which is well applied to transparentmaterials with an interlayer or transparent materials with a vacuuminterlayer.

Referring to FIG. 10, a structure of another transparent antenna isdisclosed. The transparent antenna includes a supporting body 30, afirst polymer layer 40, an adhesive layer 80, a second polymer layer 41and a covering layer 31. The first polymer layer 40 is provided on aside of the supporting body 30, and the side of the first polymer layer40 away from the supporting body 30 is provided with a concavestructure, and the concave structure is provided with a conductivematerial to form a first transparent antenna. The first transparentantenna includes a first antenna body 11 and a partition region, and thefirst antenna body 11 includes a grid-like conductive wire. The secondpolymer layer 41 is provided on a side of the covering layer 31, theside of the second polymer layer 41 away from the covering layer 31 isprovided with a concave structure, and the concave structure is providedwith a conductive material to form a second transparent antenna. Thesecond transparent antenna includes a second antenna body 12 and apartition region, and the second antenna body 12 includes a grid-likeconductive wire. And the covering layer 31 here plays a role of asupporting body, only names being with different. The projection of thesecond transparent antenna covers at least 60% of the area of thepartition region of the first transparent antenna, of course, or covers80% of the area of the partition region of the first transparentantenna, or in order to achieve better visual effect, covers more than95% of the area of the partition region of the first transparentantenna. The partition region described here is a partition region of asingle transparent antenna, or a partition region between twotransparent antennas. In the present embodiment, the first transparentantenna and the second transparent antenna cooperate with each other to“fill” their respective partition regions, in which the partitionregions may be completely “filled” or partially “filled”, in order toreduce visual difference caused by difference in transmittance. Ofcourse, in the case where there is an overlapping region between thefirst transparent antenna and the second transparent antenna, in orderto ensure a similar transmittance, the grid linewidth at the overlappingregion is less than the grid linewidth at a non-overlapping region, soas to ensure that the transmittance at the overlapping region is similarto the transmittance at the non-overlapping region. For example, thegrid linewidth at the overlapping region of the antenna body 11 of thefirst transparent antenna is 3 microns, while the grid linewidth at thenon-overlapping region of the antenna body 11 is 5 microns, so that theabsolute value of the difference between the grid linewidth at theoverlapping region and the grid linewidth at the non-overlapping regionis not less than 0.5 microns. Of course, the same is true for the secondtransparent antenna. The first transparent antenna and the secondtransparent antenna are connected with each other through the adhesivelayer 80, for example, the first transparent antenna and the secondtransparent antenna are bonded to each other “face to face” (as shown inFIG. 10). Of course, the first transparent antenna is bonded to the sideof the covering layer 31 away from the second transparent antennathrough the adhesive layer 80 (not shown in the figure), so thisstructure can also be used in electronic devices, household appliances,buildings and vehicles.

Referring to FIG. 11, another transparent antenna structure isdisclosed, and the transparent antenna structure is similar to thetransparent antenna structure in FIG. 8. The difference is that thetransparent antenna structure here includes a transparent antenna and adummy electrode, and the transparent antenna includes an antenna body 11and a partition region. The antenna body 11 includes a grid-likeconductive wire, and the dummy electrode is provided in the partitionregion. The dummy electrode includes a grid or line segments, and thegrid includes grid lines 21. Furthermore, the absolute value of thedifference between the transmittance of the antenna body and thetransmittance of the dummy electrode is not greater than 20%.Furthermore, for better visual effect, the absolute value of thedifference between the transmittance of the antenna body and thetransmittance of the dummy electrode is not greater than 10%, or notgreater than 5%.

The transparent antenna described above is applied to fields includingmobile phones, PADs, household appliances, cards requiring signalreception and transmission, windows or transparent regions of buildings,vehicles, and other electronic devices, such as watches.
